After a year of pain with Ubuntu Linux I think I will wipe it off my drive!!

I have had so much pain with it, the file system if horrid, why I can't copy folders is beyond me!! Using File Manager(or what ever it is called) how do you copy from one folder to another when you can only open one instance of it??? What ever I click on the left pane shows the contents on the right. . . Useless!!!

I tried to update to a new version and it errors during the update so really it is probably stuffed.
